Specifications include, but are not limited to: 1. Instrument will perform real-time pavement marking retroreflectivity measurements. 2. Instrument will also detect, measure, and record the location of retroreflective road studs (raised pavement markers) in the 30-meter geometry. 3. The driver/headlight geometry will be a 1/5th scaled system or otherwise scaled utilizing the ASTM E1710 and EN1436 30-meter geometry with a minimum of 12 cm of ground clearance when in use. 4. While not in use, the instrument will raise up to achieve a minimum of 7 inches (17.8 cm) ground clearance. 5. Measurement will be made 6 or 12 meters in front of the instrument to most closely mimic the driver perspective. 6. Illumination Angle will be 1,24° (per EN 1436) 7. Observation Angle will be 2,29° (per EN 1436) 8. Entrance Angle will be 88.76° (per ASTM E1710) 9. Observation Angle will be 1.05° (per ASTM E1710) 10. Measuring aspects of the total angular spread will not exceed 0.33 degree
